Saidseccured, preferably riveted together. The tions 14, during the fillingof a car with grain may be swung inwardly to aiiord suflilower end ofthe post 4 is bifurcated as indicated to form a substantiallyrectangular cient opening above the same for admission To all 'whom itmay concern:

Be it known that I, VILLIAM H. FISHER, a citizen of the United States,residing at Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Grain-Doors, of whichthe following is a specification.

My invention relates to improvements in grain doors and has for itsobject the production of a door of this character which will be ofdurable and economical construcbe more readily underto the accompanyingpart of this specifica- Amm of the grain. Upon filling of thecar saidsect-ions will be swung to vertical position and, in which position7 thesame will be held by the pressure of the grain thereon. Pivotallysecured as at 15 to the outer sides of one of each of the sections 11and 14 is a strap 16. The straps 16 are adapted to extend around theouter sides of the post 4, when the door sections are in operativeposition, the free extremities thereof 'being slotted for engagement bythe turn buttons 17 provided upon the other of the sections 11 and 14.Vhen so arranged the straps 16 will evidently serve to loclr the doorsections to the post 4, preventing inward movement thereof.

Secured upon the outer sides of the lower ends of the members 5 of thepost 4 are angular guide members 18 which are adapted to form guidechannels for a closure plate 19 which is vertically slidable therein,the

latter evidently serving as a closure for the' opening or passageway 2.

2O indicates a reinforcing `angle iron] which is secured upon the outerside of the closure 19, said angleiron also serving as a means ofengagement for the hand to effect sliding movementof the closure.

Secured to and upwardly extending from the closure 19 is a bar 21, thelatter being provided with a plurality of spaced slots 22. Said slotsare adapted to be engaged by a turn button 23 arranged in the post 4 Ydurable and is simple and whereby the closure may be held at variouselevations as desired. Provided upon the outer edges of the doorsections 11 are spaced eyes may be supported in inoperative positionsupon supporting hooks 25 arranged within the car for that purpose. Asindicated in Fig. 3 the post 4 may also be supported by one of thesupporting hooks 25 in inoperative position together with the doorsections 11. Unlawful removal of the door sections is prevented bychains 26 which serve to loclr the same, as indicated, to the car.

A door of a construction as set forth is of construction, the same maybe readily and quickly arranged in position for use, and as readily andquickly removed and arranged in inopera- 24, whereby said sections tiveposition. The provision of the opening 2 and the readily slidableclosure 19 therefor affords means whereby the grain may be readilyunloaded from the car without necessitating the removal of the sections11.

Vhile I have shown what I deem to be the preferable form of my graindoor I do not wish to be limited thereto as there might be variouschanges made in the details of construction and arrangement of parts describecl without departing from the spirit of the invention. I thereforedo not wish to be limited to the exact details set forth but desire toavail myself of such changes and alterations as fairly fall within thescope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. The combination with a car having a doorway, of a verticallyextending post having a bifurcated lower' end, said post being removablysupported substantially central in said doorway; door sections resting`against said post and against the vertical frame posts of said doorway,the said door sections being cutaway to form an opening registering withsaid bifurcated lower end; and a closure mounted upon the bifurcatedlower end of said post, substantially as described.

2. The combination with a car having a doorway, of a verticallyextending post removably supported substantially central in saiddoorway, said post consisting of two angle irons riveted together attheir central and upper portions but spread apart at their lower ends toprovide a discharge opening; door sections resting against said post,said door sections being cut away to form l an opening registering withsaid discharge l opening; and a closure for said discharge ll opening,substantially as described. l In testimony whereof I have signed my lname to this specification in the presence of l two subscribingwitnesses. l
